Sustainability In The Coal Industry Statistics

Coal still powered 36% of the world’s electricity in 2022, yet Europe cut coal generation 46% since 2015 and methane and air pollutant controls show what can shift fast when policy and technology line up. Sustainability In The Coal Industry tracks the full chain from coal mine methane and flaring through lifecycle emissions and power plant cleanup performance, alongside the capital shift toward renewables and the scenarios that project coal demand falling to 2030.

Coal still generated 36% of the world’s electricity in 2022, yet parts of Europe cut coal power by 46% between 2015 and 2022. Behind that shift, the climate and air quality tradeoffs get sharper, from methane leakage across the supply chain to the emissions controls that can dramatically change outcomes at the plant level. We pull together the most telling sustainability statistics so you can see where coal is losing ground and where the biggest emissions challenges remain.
